Title: Circulating belt-type oil separator - has a partially immersed belt, an associated mechanical scraper and entrained vane wheels for removing leakage oil from surface of coolant-lubricant emulsion
Inventor: ULLMANN ADOLF
IPC: E03F5/16
Filed: 1993-10-25
Abstract: Appts. has a partially immersed belt (4), which travels over rollers in a frame-like stand; an associated mechanical scraper (19) for collecting and discharging the leakage oil (O) to a collection tank (21); and entrained vaned wheels mounted on the shaft of the partially immersed lower belt guide roller for producing, in the contaminated emulsion (E,O), a surface flow directed towards the belt (4).

Title: Externally mixing planar burner for liquid fuels
Inventor: FESEL HEIKO
IPC: F23D3/40
Filed: 1993-11-10
Abstract: The invention relates to a planar burner having a high energy density and resistance to wear. In order to achieve a large mass-exchange (mass-transfer) surface between the fuel and oxidant, a multiplicity of tubes for feeding an oxidant are arranged in a porous combustion plate made from ceramic. The fuel is fed to the burner in the liquid state and as a consequence of the capillary action of the pores in the burner plate conveyed into the flame region and gasified there and burnt. The simple construction of the burner according to the invention, the use of ceramic materials and the high energy efficiency of the burner thereby rendered possible permit the economical use of the planar burner not only for multifarious industrial applications, but also for compact heating systems.

Title: Phase-locked circuit and integrated circuit device
Inventor: HATAKENAKA MAKOTO
IPC: H04L7/033
Filed: 1994-04-11
Abstract: The aim is to increase the operating speed of an integrated circuit device having a sequential circuit and to expand the range of phase synchronisation for carrying out data processing of the sequential circuit. The phase-locked circuit (57) is provided in the integrated circuit (50), and the clock signal (CK7) input externally through the phase-locked circuit is fed to the sequential circuit (52). The data output from the sequential circuit (52) are fed back to the phase-locked circuit (57) from the output end of the buffer (Bu56). In the phase-locked circuit (57), the clock signal (CK7) input through the buffer (Bu50) and the output data of the sequential circuit (52) are compared in terms of their phases and the phase of the clock signal output at the sequential circuit (52) is adjusted, in such a way that their phases correspond. The output data (DO7) output from the sequential circuit (52) are not delayed with reference to the clock signal (CK7). As a consequence, the data processing speed in the integrated circuit (70) can be increased. <IMAGE>

The bands are brought to the cutting points at a clearance from the cylinder turning axis equal to at least the thickness of the printed material using underlay strips (5).The circular cutters are fixed at a certain spacing to the cylinder, so that the cutters only contact the bands at the points of greater clearance from the turning axis and only cut or perforate the printed material at these points.
Patent DE-4416518-A1 (DE)
Inventor: DOMMER ARMIN
IPC: B29C35/08
Filed: 1994-05-10
Abstract: The proposal is for a device for butt-welding plastic sections, especially pipes. The sections to be welded are coaxially positioned and relatively axially moved by means of clamping devices. The faces of the sections to be welded are taken to the necessary welding temperature by a heating device (15) which can be fitted between them. The heating device (15)consists of at least one flat resistance heating element (19) to apply infra-red radiation directly to the faces of the sections. Protective plates of infra-red-transparent glass-ceramic material are arranged at a distance from the section faces as separate plates between the heating element (19) and said faces. The direct heating of the faces of the sections to be welded by the heating element makes very fast, energy-saving heating to the necessary welding temperature possible, while the protective infra-red-transparent glass-ceramic contact prevention plates have a negligible effect on the heat transmission.

Patent DE-4437386-A1 (DE)
Inventor: BUECHERS GEORG
IPC: C02F3/12
Filed: 1994-10-19
Abstract: The invention pertains to along-known process for long-term aeration of waste waters laden with biodegradable pollutants in a channel or tank having a circular flow. The waste water is kept in circulation by conveyors. The oxygen needed for decomposition is drawn from the ambient air by surface aeration using at least one horizontal-axis (8) rotary aerator (7) with a plurality of rigid beaters. The invention provides that the aeration is controlled completely separately from the circular flow in that the impact and passage direction of the beaters is transverse to the circular flow produced by the conveyors, and that on their front side in the direction of movement, the beaters have a shape conductive to a low-energy circumfluence and/or a very small on-flow surface. As a result of the process features, the air bubbles introduced by the beaters are immediately carried away from their point of entry. Since the new rotary aerator (7) no longer produces a directed off-flow, its effectiveness and economy be regulated independently.

Abstract: Selon un procédé de contrôle d'un capteur de valeurs de consigne d'entraînement, on déduit une défaillance de l'actionnement des freins et de l'immobilité du capteur. En cas de défaillance, la puissance du moteur tombe jusqu'à une valeur réduite, ce qui permet de freiner le véhicule, par exemple lorsque la pédale de l'accélérateur est bloquée. D'autre part, ce circuit de sûreté ne réagit pas lorsque le déplacement du capteur de valeurs de consigne indique que le conducteur du véhicule souhaite obtenir une puissance accrue du moteur.
